Synopsis
Excerpt from Tables for Qualitative Chemical Analysis: Arranged for the Use of Students
In these tables, primarily prepared for the use of my own students, I have made an attempt to combine some of the advantages of Quantitative methods with the processes of Qualitative Analysis. It is assumed that the student using these tables has been through a preliminary course of practical instruction, including such matters as glass working, the use of the blowpipe, an instrument far too much neglected nowadays, the preparation of the gases and of certain salts, etc.
The experiments upon the preparation of gases, salts, etc should also be carried out upon Quantitative methods, i.e., the quantities of the materials necessary for their preparation should be calculated and weighed out or measured by the student himself.
In the case of gases, he should also be required to measure the capacity of the gas jars intended to be filled and to correct their contents for tempera ture and pressure.
This part of the experimental work will thereby afford far better training, be more instructive and more interesting to the beginner than the usual routine arithmetical questions upon the preparation of given volumes of gases and the correction for temperature and pressure.
